Convergent validity of shoulder range of motion measurement methods in breast cancer patients

Key Points

• The study aims to assess the convergent validity of different shoulder range of motion measurement methods in breast cancer patients.
• Comparison of humerothoracic and scapulothoracic range of motion measurement methods
• Evaluation of clinical tools and inertial measurement units
• Analysis of differences in measurements from different methods
• Clinically significant differences found for scapulothoracic range of motion
• Results suggest measurement tools should not be used interchangeably
